Hi guys.. I have a small issue with my idle when coming to stop or taking the car out of gear to come to a stop. I notice the idle drops and the car shakes, then it pics up and idles OK. I changed the plugs, PCV valve and my car has an after-market intake on it. No CEL at this time. Other threads say something about resetting the ECU or replacing the map sensor but I’m not a mechanic so I’m not sure I can do those on my own. Any thoughts??

Have u tried cleaning the throttle body?

 

Yea I have the same issues, but mine only happens when I come to stop from 30MPH and down. But if I come to a stop from a higher speed then it doesn't happen.

 

no... any posts with pics on how to do this??

 

Ive seen a couple DIY of this on the foums.

 

I had the same problem and it turned out to be a failed or faulty gas cap! See if you notice a stronger than normal fuel smell around cap. Mine finally coded an evap problem which led me to get a new cap and it solved idle problem instantly.

 

I have this problem too, but only with the AC on. If I blip the throttle a bit, like backing out of a parking spot, when i let off, it idles down and shakes pretty bad. But with the AC off, it's fine.

 

yeah mine does that with the AC off. Ill check the gas cap but cannot find any DIY on cleaning the throttle body...

 

mine dose this and always has

 

Mine does this too but I wouldn't think it's a big deal though. It happens on other cars too but I believe our s2000 is just more noisyER and vibrates more.
